Boron-doped diamond (BDD) is presently the subject of considerable interest as an electrode material. This is a consequence of its very wide potential window in aqueous solution (ca. -1.3 to +2.3 V versus the normal hydrogen electrode), low background currents, and corrosion stability in aggressive media. Diamond electrodes have indeed the largest potential window so far measured in aqueous electrolytes. This makes them also totally different to common electrode materials such as gold, platinum, or mixed metal oxide DSA-type electrodes. They are chemically stable and resistant to thermal shock and exhibit extreme electrochemical stability, and this has been considered as one of the major advantages of doped-diamond electrodes compared to conventional electrode materials.

Because of their unique electrochemical properties, doped diamond electrodes can be used for a huge number of applications. Since their properties largely differ from that of conventional electrode materials, in most cases they will not replace these materials but will make electrochemical processes possible that were not before. So far, because of their wide range of applications, studies to contribute to the advance of the fundamental knowledge of this material are strongly important for their further technological application.

We invite investigators to contribute with original research articles as well as review articles that will stimulate the continuing efforts to understand the relation between the properties of diamond materials and their electrochemical behavior as well as new insights and trends in the applications of this material to solve a wide range of technological problems and/or improve processes or systems. Potential topics include, but are not limited to:

• Fundamental studies of BDD electrodes: synthesis, preparation, and characterization
• Industrial applications of BDD electrodes: water treatment, oxidants production, ozone formation, water disinfection, and energy conversion
• Application of BDD electrodes for inorganic or organic electrosynthesis
• Electroanalytical applications of BDD electrodes: detection, quantification, surface modifications, and development of sensors
• Bioelectrochemical applications: diamond biosensors and sensors
• Nanodiamond electrodes
• BDD electrodes used in spectroscopic applications
• Emerging BDD technologies: electro-Fenton, photo-electro-Fenton, neurochemistry, pulse detection, and ultra-microelectrodes
• Future applications of BDD electrodes
